Sums it up. Silva could keep the ball as long as you wanted him to have it but had the killer pass in his locker and would use it like a stilletto - the setup in the 6-1 I replayed endlessly for months. KDB will take far more risks with the ball and capable of some outrageous hollywood type balls , when he has an off day can look awful (not too many mind) and when bang at it can destroy teams like he did away to Wolves - think that was the best individual display I have seen from him but the goal away at Chelsea , this seasons game at home to arsenal and Madrid away all part of brilliant performances.
If I was forced to pick one , it would be KdB purely on the basis he would win you more games on his own but I reserve the right to change my mind in ten minutes when I have thought about it some more !!!
